HM/E01 Plug-On
Transmitter

15 September 2017

Digital Hybrid Wireless

®

U.S. Patent 7,225,135

LECTROSONICS, INC.2

The HM Digital Hybrid® UHF plug-on transmitter features a DSP-based
design that allows the transmitter to operate in its native Digital Hybrid Wire­less

®

mode, Lectrosonics 200 Series, 100 Series, IFB product groups, plus
three modes for compatibility with analog receivers from other manufacturers.
A unique multi-voltage phantom power feature allows the transmitter to be
used with virtually any microphone, including high-current condenser types,
expanding its usefulness in high-end applications such as motion picture
production.

The transmitter provides up to 1024 frequencies selected with the membrane
switch keypad. The input amplifier uses an ultra low noise op-amp for quiet
operation. It is gain controlled with a wide range dual envelope limiter, provid­ing over 30 dB of headroom above full modulation. A 24-bit A-D converter
digitizes the audio, then filters supersonic noise above 21 kHz. The resulting
signal is encoded with a proprietary algorithm to produce an analog data sig­nal for RF transmission. The underlying RF link is an optimized FM system
with +/-75 kHz wide deviation for a high signal to noise ratio.

The antenna is formed between the lower housing of the transmitter and the
attached system. It functions as a dipole radiator when attached to a hand­held microphone and somewhat like a ground plane antenna when con­nected into a mixer. The conical shaped collar on the input coupler is made
of DuPont

TM

Delrin® to improve the ERP of the antenna in the uppermost

frequency blocks.

The HM transmitter is powered by two AA batteries. We recommend using
lithium batteries for longest life. Lithium batteries provide approximately 9
hours of operation at room temperature, without phantom power enabled.

The battery status circuitry is designed for the voltage drop over the life of
lithium batteries.

To install new batteries:

1) Slide the battery compartment door outward and swing it open.

2) Insert the new batteries into the housing. One battery goes in positive (+)
end first, the other negative (–) end first. Look into the battery compart-
ment to determine which end goes in which side. The side with the plastic
ring and smaller round opening is the side which must contact the (+) posi­tive end of the battery. The other battery is inserted in the opposite polarity.

Note: It is possible to install the batteries backward and close the
battery door, but the batteries will not make contact and the unit will not
work.

3) Close the Battery Cover and slide it inward until it snaps shut.

The Frequency Screen displays the operating
frequency in MHz or as a two-digit hexadecimal
number that corresponds to the equivalent
Lectrosonics Frequency Switch Setting. The
example of the two-digit display shown here
indicates CH (channel) and 2C as the frequen­cy. Repeatedly pressing the FREQ button
toggles between the two displays. Press and
hold the FREQ button and use the Up and

Down arrows to select the frequency.

Set Up in 25kHz Mode

in MHz

The operating frequency of the HM is displayed
either in MHz or as a two-digit hexadecimal
number. Pressing the FREQ button toggles
between the two display modes. The frequency can
be set with the unit in Standby Mode or while
powered up for normal operation.

Note: You must first find a clear frequency
with the receiver, then set the transmitter to
match.

To change the Operating Frequency of the HM

transmitter:

1) Press the FREQ button to enter this screen.

2) While holding the FREQ button, use the UP or DOWN arrow buttons to
move the operating frequency up or down in 100 kHz increments from the
current setting. Holding the UP or DOWN arrows will cause rapid scrolling
through the frequencies.

Note: The operating frequency displayed on the LCD wraps as it
reaches the upper or lower end of its range.

Attaching a Microphone and Adjusting the Gain

TO AT TACH

TO REMOVE

Hold the
transmitter
case with the
microphone
pointed
upward.
Rotate the
collar in the
direction
shown.

Pull on mic to ensure it is locked.

Press firmly, listen for click.
Depress collar fully.

Click!

To attach the mic, insert the
HM into the XLR connector.
Press the connector into the
microphone until the tapered
collar retracts and listen for a
“click” that indicates the
connector has locked onto the
microphone. Gently pull on the
mic to ensure proper locking

has occurred.

When removing the microphone from the HM, hold the transmitter in one
hand and twist the collar with the other hand until the microphone disengages.
Do not pull on the microphone as it may prevent the connector from releasing.

The front panel Modulation LEDs indicate limiter
activity. (See chart below.) Once set, the transmit-

ter’s audio level setting should not be used to
control the volume of your sound system or recorder levels. This gain adjust­ment matches the transmitter gain with the microphone’s output level, the
user’s voice level and the microphone’s position. The audio input level can be
set with the unit in Standby Mode or powered up for normal operation.

Signal Level -20 LED -10 LED

Less than -20 dB

Off Off

-20 dB to -10 dB

Green Off

-10 dB to +0 dB

Green Green

+0 dB to +10 dB

Red Green

Greater than +10 dB

Red Red

Different voices will usually require different
gain settings, so check this adjustment for
each person using the system. If several
different people will be using the transmit­ter, set it for the loudest voice.

1) Set the required phantom power mode
before attaching the microphone.

2) Briefly press the AUDIO and FREQ buttons at the same time, then press
and hold the AUDIO button to enter the setup screen.

3) Use the microphone in the manner in which it will be actually used.

4) Observe the HM audio level LEDs while speaking or singing into the micro­phone at the same voice level that will be used during the program. While
holding the AUDIO button, press the UP or DOWN arrow buttons until the
both the -20 and -10 LEDs glow green, with the -20 LED occasionally flick­ering red (+0 dB to +10 dB range during peaks).

Note: Setting the audio level too high reduces the dynamic range of the
audio signal. Setting the audio level too low may cause hiss and noise
in the audio.

Using the Polarity-Reversing
Barrel Adapter with
Measurement Microphones

A polarity adapter may be needed if
you experience noise, low output or
distortion with meaasurement micro­phones such as Earthworks M30 or
Rode NTG3.

Insert the barrel adapter provided with
the HM transmitter between the micro­phone and transmitter as shown.

NOTE: This adapter is included
with the TM400 test and
measurement system, but is
available as a separate item
with the HM transmitter and
other wireless equipment.

Important: The only way to unlock a locked transmitter is to remove the
battery. It cannot be unlocked or powered off using the buttons. The unit will
always power up in “unlocked” mode.
